Perhaps it was an error to mix sysread [1] with print (as noted in the documentation, even though the handles are different). Can you try syswrite [2] in the three lines here [3] instead of print, please? Kind regards Felix Lechner [1] https://perldoc.perl.org/functions/sysread [2] https://perldoc.perl.org/functions/syswrite [3] https://salsa.debian.org/lintian/lintian/-/blob/master/lib/Lintian/IO/Select.pm#L192-194
